Uma Thurman 'Doing Well' After Giving Birth to a Baby Girl

The girlfriend of Arpad Busson is confirmed to have delivered a baby girl on Sunday, July 15.

Uma Thurman, who announced her pregnancy last February, has welcomed a baby girl. The Bride of the "Kill Bill" movie series gave birth to her bundle of joy on Sunday, July 15, her representative confirmed to PEOPLE. "Mom and baby are doing well," the publicist additionally said.

The little girl is Uma's second daughter and third child overall, but the newborn is her first with financier boyfriend Arpad Busson. The baby joins sister Maya, 14, and brother Levon, 10, from her previous marriage with actor Ethan Hawke.

Uma, 42, has been dating 49-year-old Busson since 2007. They briefly split in 2009, but were back on each other's arms ever since. Busson himself has already had two sons, Flynn, 14, and Cy, 9, with Elle Macpherson. He got engaged to the supermodel from 2002 to 2005.
